AWS Cloudwatch interview Questions & Answers

Ques: 5). Tell us about your proudest achievement.

Answer:

My most significant accomplishment was in my former work as a cloud specialist. I worked for a firm that was experiencing a shortage of cloud professionals at the time. Adding more cloud professionals to the tea sounded expensive because the company was small. I recommended to the company's president how we could automate some tasks. I helped him because he didn't know what to do. Some operations, such as backups at specific intervals and resource pattern monitoring, become simple to automate.

kill – To kill a process using the process id kill command is used. ps command provides details on process id. To kill a process issue kill pid.

killall proc – This command is same as kill command. To kill all the processes by name proc we can use this

Ques: 12). In Amazon Web Services, Emphasize The Importance Of Buffer.

Answer:

An Elastic Load Balancer ensures that incoming traffic is spread as efficiently as possible across multiple AWS instances. A buffer will synchronise several components and make the setup more elastic in the event of a burst of load or traffic. The components are prone to receiving and processing requests in an unreliable manner. The buffer produces an equilibrium between diverse devices and crafts them to function at the same rate, allowing for faster service delivery.

Ques: 13). What Is An Amazon Web Services Availability Zone?

Answer:

A collection of your AWS resources is made up of availability zones (within a region). For high availability and fault tolerance, properly built applications will use several availability zones. Each AZ has a low-latency direct connection to the others, and each AZ is separated from the others to ensure fault tolerance.

Ques: 14). What Happens When A User Types A Domain Name Into A Web Browser?

Answer:

A DNS server is contacted by the web browser, which requests the IP address associated with the domain name.

Ques: 19). Do you understand how the internet works in your area?

Answer:

There are several internet tiers and web servers available all over the world, which serve as the internet's communication path. Without the internet's ingenuity, sharing could not have progressed as quickly as it has.

Circuit switching is a word used on the internet to describe how the internet works in your current context. Another internet technology is packet switching, which makes it much easier for the internet to communicate or distribute information. This is one of the most common AWS cloud support engineer interview questions because it gives you some fundamental internet knowledge.

Packing switching is the process of separating a single internet server into numerous servers. There is no requirement for a physical path for the computer. The internet's supporting equipment would be sufficient to enable better and more dependable internet sharing among a large number of computers.

Ques: 20). In Linux or UNIX-based operating systems, how can you easily manage processes?

Answer:

When a user types a command into a Unix operating system, it starts working. When an operating system is started, an instance is created automatically. To manage processes in Linux OS, I would use the PS processing command. This command displays information about the currently running processes and activities. When running Linux, I can also use TOPIS as a process management tool.

This command can be used to acquire statistics about the operating system's activity. To kill running processes, I would also use the Kill command. In a Linux-based operating system, press Ctrl+Alt+Del to terminate all programmes. I would use the killall command. With these commands, I would be able to take full control of the operating system and manage its processes effectively.

Oracle SCM Interview Questions and Answers

Ques: 6). How does the payment system operate?

Answer:

An account's open items can only be removed if an identical offsetting amount is posted to the account. To put it another way, the sum of the things assigned to each other must equal zero. The system enters a clearing document number and the clearing date in these objects during clearing. Invoices in a vendor account are marked as paid, and items in a bank clearing account are marked as cleared in this fashion.

In most cases, the payment program is used to settle invoices. As a result, manual clearance of open items is rarely required. However, you may have to manually remove objects on occasion if, for example, you receive a refund from your vendor or you have set up a direct debit procedure.

Oracle PL/SQ L Interview Questions and Answers

Ques: 9). What's the difference between interface and base tables?

Answer:

The following is a comparison of the interface and base tables.

Interface table: The interface table is where the data is checked before being posted to the base tables. Oracle is seeded in a large number of interfaces. You can think of the interface as the data's entry point, and it checks the data's sanity.

Base tables: As told earlier once the data is validated will get updated in the base tables, and is considered as the data which is in the base table is accurate and used in many ways. (Reporting..etc..)

The base tables in AP are as follows:

1) ap_invoices_all

2) ap_invoice_payments_all

3) ap_invoice_distibutions_All

4) ap_payment_schdules

5) ap_payment_dustributions_all

Oracle SQL Interview Questions and Answers

Ques: 10). How many different forms of buy order agreements/orders are there?

Answer:

A) Standard Purchase Order: Standard purchase orders are used for one-time purchases of a variety of items. When you know the specifics of the goods or services you need, as well as expected pricing, quantities, delivery schedules, and accounting distributions, you may write standard purchase orders. Because the required information is known if you use encumbrance accounting, the purchase order may be encumbered.

B) Planned Purchase Order: A planned purchase order is a long-term commitment to purchase items or services from a single supplier. You must include preliminary delivery dates as well as all specifics for the items or services you wish to purchase, such as the charge account, quantity, and anticipated cost.

EXAMPLE: Buying Christmas gifts from a specific retailer.

C) Contract PO: You form a contract purchase agreement with your supplier to agree on particular terms and conditions without specifying the items and services you would be purchasing, such as "for $ amount, you must supply this much quantity.” You can then issue ordinary purchase orders referencing your contracts, and if you use encumbrance accounting, you can encumber these purchase orders.

D) Blanket Purchase Agreement: You construct blanket purchase agreements when you know the details of the items or services you expect to buy from a specific provider over a period of time but not the details of your delivery schedules. Before actually acquiring your things, you can use blanket purchase agreements to define negotiated rates.

A Blanket Purchase Agreement is a type of contract between you and your supplier that specifies the price at which you will buy products from them in the future. The price of the item, not the quantity, is entered here. The amount of the items is entered when the release is created. In the release, there is no way to change the pricing. The Released Amount is calculated by multiplying the amount by the price. Assume you have a contract with your supplier that states you can only buy products worth a certain amount against the contract.

To accomplish this, we'll need to design a single recurring invoice template. The term "template" refers to the process of making several invoices from a single master copy. We're making a single invoice master copy, which is also known as a recurring invoice or recurring invoice template.

SET UP:

1) Create one special calendar

2) Create one full distribution set

3) Enter payment terms in the recurring invoice window

4) Enter the template no, first invoice amount, special invoice amounts

BI Publisher Interview Questions and Answers

Ques: 12). What Are The Different Types Of Holds That Are Used To Prevent Invoice Payment?

Answer:

Holds that we can manually apply or that Payables automatically apply to block payment and, in some situations, the generation of accounting entries for an invoice. We can manually release specific holds that Payables applies during Approval, and we can remove holds that we apply.

Payables offers us with some default invoice holds, and we can construct our own based on our invoice approval requirements. We can also put a hold on the supplier rather than on each individual invoice to prohibit payment of supplier invoices.

There are two major category of hold

Manual Hold

System Hold.

Manual hold we can create and release manually where as system hold is created by system and normally released by system after due rectification.

There are three types of holds we can use to prevent payment of an invoice

Invoice Hold:We can manually apply one or more Invoice Hold Reason Approvals (”holds”) to an invoice using the Invoice Holds window of the Invoice Workbench.

Scheduled Payment Hold: We can hold payment on part of an invoice by placing one or more of the scheduled payments on hold in the Scheduled Payments window of the Invoice Workbench.

Supplier Hold: In the Supplier Sites window, we can enable the Hold All Payments, Hold Unapproved Invoices, or Hold Unmatched Invoices options. We also have the option of specifying an Invoice Amount Limit for a supplier site.

Ques: 14). What is the difference between Oracle Payables' Primary and Secondary Ledgers?

Answer:

The Primary Ledger is the Main Ledger, while the Secondary Ledger is the Replica of the Primary Ledger. All of our transactions are recorded in the Primary Ledger. The main reason for using Primary and Secondary Ledger is the discrepancy between the Organizational and Statutory Requirements.

For example, a US corporation with an office in India has a calendar that runs from October to September, but the Indian calendar goes from April to March. This is when the notion of the Primary and Secondary Ledger comes into play. Whereas the primary calendar might be designed according to US standards, However, according to India's Statutory Requirements, the secondary calendar is used.

Ques: 15). What Are The Approval Levels That Match?

Answer:

We can execute online matching of invoices and original purchase orders or purchase order receipts if we utilise Oracle Payables with Oracle Purchasing or another connected purchasing product. Matching ensures that we only pay for the items and services we requested, and that our vendors do not overcharge us. The Payables Approval Program applies holds to invoices that exceed the amount and quantity tolerances we establish, preventing payment until the holds are released.

Ques: 16). How does the payment system operate?

Answer:

Open items on an account can only be cleared if an equal and opposite amount is posted to the account. To put it another way, the total number of items assigned to each other must be zero. During clearing, the machine enters a clearing document number and the clearing date in these items. Products in a bank clearing account are marked as cleared, and invoices in a vendor account are indicated as paying.

The payment programme is typically used to settle invoices. As a result, removing open things manually is rarely required. You may need to manually clear products if, for example, you request a refund from your supplier or have set up a direct debit mechanism.

Ques: 17). What should be the setup steps when i wish to implement TDS features only?

Ques: 18). What causes the Error? When attempting to match an invoice to a PO, does App-Sqlap-10715 appear?

Answer:

When an invoice is matched to a PO for the complete quantity, the PO is ready for invoicing. If the invoice line is rejected (using the Discard button), the Match button becomes available again, reversing the PO match, and the invoice is matched to the same PO for a different quantity. The following message appears at that time: APP-SQLAP-10715: For invoicing purposes, this purchase order line has been closed. Before continuing with this match, you might want to look over the purchase order.

When we trash a line in R12, the status is only updated at validation time. When we match or reverse POs, we update the quantity billed and amount billed, but the status is only affected when we validate the invoice. Validate the invoice before proceeding with any other actions on the invoice after pressing the Discard button. For more information, see Doc ID 456370.1 and Bug 5927520.

Ques: 19). How a PO Match comes over as Exclusive Tax Lines for a reason?

Answer:

Taxes are always exclusive in PO, unless otherwise specified in the PO application/product design. As a result, in AP, taxes on an invoice linked to a PO are calculated as exclusive taxes. More information may be found in Bug 6748767 R12: APXINWKB - JAPAN INCLUSIVE TAX, PO MATCH COMES OVER AS EXCLUSIVE TAX LINES. For more details, see Doc ID 549988.1.

Ques: 20). What Are Offset Taxes and How Do They Work? What Is It Used For?

Answer:

Offset Taxes: Offset tax codes are used on invoices to record self–assessed taxes while reducing or totally offsetting tax burden. Because offset taxes have negative–amount rates, you must input negative–amount invoice tax distributions when using them.

It is utilised in the European Union, and if you are a member of the EU, you can use the Intra–EU VAT Audit Trail report to report on these zero–rated taxes.
